When the transfer is completed type bye and then press "Enter"
Note: These steps may vary depending on the FTP client and whether it is on a Linux or
Windows PC. The login information, file names, and destination folder are the same in
both cases.
10.5 Network Restarting
To restart networking from the terminal command line do the following:
Type: /etc/init.d/networking restart and then press "Enter"
10.6 RAID (Partitions)
Two partitions are present in the ShowVault. One partition is “/dev/md0” which is mounted on
“/data” and another partition is ‘/dev/md1” which is mounted on “/opt”. The following sections
explain how to check the health of the RAID (see Section 10.6.1) and how to reinitialize the
RAID (see Section 10.6.2).
10.6.1 RAID Failure Identification
To check the health of the RAID open a new terminal and login as “root”
Type: more /proc/mdstat and then press "Enter"
On a healthy RAID the command below will appear:
Personalities : [raid5]
md1 : active raid5 sda1[0] sdb1[1] sdc1[2]
21125248 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]
md0 : active raid5 sda2[0] sdb2[1] sdc2[2]
760291968 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]
On a failed RAID the command below will appear:
Personalities : [raid5]
md1 : active raid5 sdb1[1] sdc1[2]
21125248 blocks level 5, 64k chunk, algorithm 2 [3/2] [_UU]
md0 : active raid5 sdb2[1] sdc2[2]
760291968 blocks level 5, 64k chunk, algorithm 2 [3/2] [_UU]
In the failed example above, the hard disk drive “/dev/sda” is failed. This failure could be
the result of a hardware failure or it could simply be that the user inadvertently pulled the
drive out.
